Under what conditions does the trp repressor block transcription of the trp operon? (A) when the repressor binds to the inducer
Brilliant_brown [7]

The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.

trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.

Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.

Hey, do you think you can help me with these questions? I'll give some extra points(can give more if needed)
rjkz [21]

Answer:

1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars <u>will turn into</u> black holes if the force of gravity breaks the resistance of electrons.

2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.

3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.

4. A convection zone transfers energy by radiation and conduction.
